At constant boost, the RPMs of the turbo will be lower at lower engine rpms
when compared to the rpms of the turbo at higher engine RPMs.  It takes much
more air/gas mixture to fill the cylinders at 6500 RPM than at 2000 RPM so
minimal boost at 6500 RPM will have the turbos spinning faster than at full
boost at 2000 RPM.

Hope that makes sense.
